CVE-2022-29465Network attack vector

Memory corruption via unchecked PSD heap write

Published Aug 5, 2022 · Updated Apr 15, 2025

Out-of-bounds write in Accusoft ImageGear 20.0 allows attackers to corrupt memory by loading a malformed PSD file. The allocation_function_mem routine writes past an undersized heap buffer because PSD header processing omits a memory-bounds check. An application must pass attacker-controlled PSD content to the library; the resulting corruption can crash the host process or permit code execution.
